In this ducklightful animated feature film, Daffy Duck opens up the ghostbusting Ghouls R' Us Agency. "It's supply and demand," the spook sleuth explains. "My clients supply the ghosts. And I demand the money." Highlights include Daffy "Anything for a buck" Duck pitching his wares on TV; a house call to aid a vampy seducktress; a ghost-to-ghost hookup with Zed Toppel on Frightline; and, talk about a tough crowd, crooner Daffy wowing a nightclub of Transylvanian baddies.
Bugs Bunny, Porky Pig, Tweety and Sylvester join the exorcise in hilarity, with principal voices provided by the always masterful Mel Blanc. The gang's all here - and so is the fun. You'll quack up over Daffy Duck's Quackbusters!

Sylvester is determined to get a woodpecker that just moved in, high in a tree. He climbs, but the bird greases the tree; he starts to cut it down, but a mean dog stops him (this becomes a running gag). Several other attempts follow; at one point, he puts his paw into the bird's home, and the bird puts a tomato there; Sylvester squishes it, and the bird dresses as an angel to torment him, but Sylvester sees through the disguise. Finally, Sylvester tries to blow up the tree; the dog again intervenes. Sylvester gets the dynamite off the tree and puts out the fuses, but the bird has lit them again, and now Sylvester really becomes an angel.
